Along with the more expensive 6 series, the 5 series represents a real improvement in Roku TV design. The ribbon-thin frame around the TV is matte black metal, the same as most of the backside, and seen in profile the top two-thirds of the cabinet is ultraslim too, less than half an inch deep on my 55-inch review sample. The bottom third widens appreciably, to accommodate inputs, the power supply and other guts, but overall the look is modern and much nicer than the Vizio E.
The 5 series shares the 6’s “enhanced” Roku TV remote. It keeps the standard simple design of other Roku TV clickers, adds a built-in mic for voice functions, and communicates with the TV without needing line of sight.
